Ive read through some of the existing threads regarding air filtration and was inspired to build one myself. I had some leftover OSB and a few odd lengths of 2×3, and ended up with this for only the price of the blower and filters. The suction end of the blower is about 2” away from the rear filter, and the exit point is sealed off from the remainder of the system., It accepts two 14×14 filters and although the harbor freight blower does not move as much as it claims to (my interpretation), it works pretty well, it does seem to move a fair amount of air. This blower was really the only one for a doable price I could get my hands on. The normal blower of choice by many, I have yet to find for a reasonable price. This is not my end all system, I would like to upgrade once I get a stronger blower and use this as a secondary, or use the HF blower for something else all together. This is my system for now however.
Anyway, I was looking for any advice on how I could upgrade this. Specifically near the rear where the air blows out. I see a lot of people use HVAC registers, and wasn’t sure just how beneficial using one of these would be. As I understand it to direct air in separate directions, I was apprehensive about installing one because of the thought that maby it would not let enough air escape, and create a back-up in the system.
Anyway, Im just looking for any advice on this topic, and how i can improve this design. Like i said, this is not my end all system, but I would like to get the most out of it. Surely my GF (she who painted it) would hate to see me hack this one apart and re-do it, but if I can get much more out of this blower I bought, I would only be out the time it took to put it together. I think it works well enough as is, but I have nothing to compare it to that ive seen in person.
By the way, for anyone who has built these. About how strong of a suction do you get with your set-ups? Mine is def. sucking air, it will pull a tissue toward it etc., already the filter shows signs of use, but I am not overly impressed with the amount of suction I can feel, especially with two filters in place. Are these systems, bought or made, supposed to have a very impressive amount of suction to function properly, or does just a little bit go a long way?
Thanks for any input.
